Natrium Alginate and Graphene Nanoplatelets-Based Efficient Material for Resveratrol Delivery.
Gels
December 2024
Department of Physiology, Iuliu Haţieganu University of Medicine and Pharmacy, Clinicilor 1, 400006 Cluj-Napoca, Romania.
In this study, alginate-based composite beads were developed for the delivery of resveratrol, a compound with therapeutic potential. Two formulations were prepared: one with sodium alginate and resveratrol (AR) and another incorporating graphene nanoplatelets (AGR) to improve drug release control. The beads were formed by exploiting alginate's ability to gel via ionic cross-linking.

Article Synopsis
- - Brugada phenocopy (BrP) is characterized by a Brugada-like ECG pattern and can occur due to various conditions, but it doesn't increase the risk of serious heart issues like Brugada syndrome (BrS) does.
- - A case is presented of a 69-year-old woman with moderate hyponatremia who exhibited a saddle-back ST-segment elevation on her ECG, which was linked to her liver metastases compressing her heart.
- - The ECG changes resolved quickly after treating her hyponatremia with sodium chloride, demonstrating that even mild electrolyte imbalances can lead to BrP when compounded by other factors like mechanical heart compression.
Term Delivery Complicated by Uterine Rupture with No Prior History of Cesarean Section or Uterine Curettage Following Oxytocin Use and Arrest in Second Stage of Labor: A Case Report.

BACKGROUND Uterine rupture during delivery in an unscarred uterus may be associated with oxytocin dose during second stage arrest and with underlying maternal factors. This report is of a 34-year-old woman, gravida 5, para 3, with no previous history of cesarean section (CS), who had a uterine rupture at term delivery following the use of oxytocin for second-stage arrest. CASE REPORT A 34-year-old Afghani woman, gravida 5, para 3 was admitted at term for delivery.

Materials (Basel)
May 2023
Faculty of Mechanical Engineering and Naval Architecture, University of Zagreb, Ivana Lučića 5, 10000 Zagreb, Croatia.
In this paper, an innovative sustainable method of producing metal foams was presented. The base material was aluminum alloy waste in the form of chips obtained by machining process. The leachable agent, used to create pores in the metal foams, was natrium chloride, which was later removed by leaching, resulting in metal foams with open cells.

This paper aims to investigate the mechanical and rheological properties of magnetorheological elastomer (MRE) in marine ecosystems. The prepared samples comprised silicone rubber (SR) and 70 wt% micron-sized carbonyl iron particles (CIPs), immersed in an artificial marine ecosystem using salt water (Natrium Chloride) for 30 days. The mechanical properties of MRE samples were evaluated using hardness and quasi-static tensile tests.
